Kraln:Man, fluorine compounds are super nasty. To give you an idea, Fluorine will bind with noble gasses--yeah, you can have NeF8. Why the hell would you put fluorine anywhere near a car?

As already mentioned, XeF8 is possible, but not NeF8.

On the other hand, "Things I Won't Work With" features some other "interesting" fluorine compounds, especially ClF3 (chlorine trifluoride). Anything that can set sand and asbestos (!) on fire isn't going to be something I want to be around.

No, you can't have NeF8. Not yours.

Fluorine will make stable compounds with xenon, which in reality is pretty slutty for a "noble" gas. It'll bind with krypton, too, but not very stably. It'll also "bind" with argon, if you call "staying in an ordered lattice at cryogenic temperatures for the sake of the kids" "binding".

If you're concerned about the hazardous properties of the elements that compose a compound, I hope to hell that you never have to deal with table salt.

The Daily Fail is attention-whoring here for the most part; all those horrid toxic products will also appear if you propel atomized oil against an igniter with R-134a, or good old non-toxic ozone-destroying dichlorodifluoromethane. I am a bit concerned about the trifluoroacetic acid decomposition product, though. I'd be much happier sticking with R-134a for legacy systems and moving new ones to CO2, although I thought there were dire practical barriers to small-scale CO2-based refrigeration.
